This looks to be a very intriguing way to upgrade a pre 04 919 set of forks for a very good price
Very interesting comments within re SKF:
Got seals? Replacing your fork seals during a revalve is always a good idea. Don't settle for the sub-standard quality of bargain fork seals. For years I preached that only Honda OEM seals were worth putting into forks - all others were junk. Well, that's been true.... until now. The SKF brand has been highly regarded in commercial and industrial applications and finally they have released parts for motorcycle applications. These seals have the same quality, durability, and wear resistance of Honda seals with much less friction. Looking for that little bit extra? These might be just what you are looking for!
CAUTION: there is more to picking out seals on your own, than just using the basic sizing and sealing, so it would be nice to find out what SKF P/N he is using.
